RAIL DRILLING MACHINE Application AugustZS, 1930, Serial No. 477,283

4 Claims. (Cl. 778) My invention relates to an improvement in drills and has for one purpose the provision of a drill and drill structure applicable to drilling rails of railroad tracks. Another Objectis the provision, in such a structure, of means for readily and easily adjusting the height of the drill. Another object is the provision of adjustable abutment means, removably mounted in relation to the drill supporting structure, for engaging the side of the rail opposite to the drill. Another object is the provision of a light and easily mov- `able drill structure which may, for example, be manually transported .along a rail. Other objects will appear from time to time in the course 5 of the specificationand claims.

vI illustrate my invention more or less diagrammatically in the accompanyingdrawings, where- 1n Figure 1 is a side elevation illustrating the structure in transporting position;

Figure 2 vis a side elevationillustrating the structure in operating position;

Figure 3 is a plan view;

Figure 4 is a section on the line 4 4 of Figure 2;v

Figure 5 is a section on the line 5-5 of Figure 1;

Figure 6 is a partial side elevation; and Y Figure '7 is a section illustrating the rail engaging abutment and its connection with the drill structure. y

Like parts are indicated by like symbols .throughout the specification and drawings. I. Referring to the drawings, A generally indicates the roadbed of a railroad track, upon which are mounted ties A1 carrying rails A2.

B generally indicates the main frame which includes angle irons B1 forming sides to a longiltudinally extending end. The angles B1 are connected at one end by the transverse angle B2 `and at the other by a cross piece or plate B3. At each end of the frame, secured respectively to the angle B2 and the plate B3 are the upwardly extending angles B4 B1 to which may be welded or otherwise secured transverse plates or strips B5, through the outwardly extending ends of .which are inserted the supporting or carrying shafts B6. They may be held in position for example by cotters B7. It will be seen for example from Figures 1 and 3 that the ends` of the shafts B6 project sufficiently outwardly at each end of the drill structure to permit an operator to stand between the shafts and engage each A shaft with one handin the manner of the carrier of a sedan chair.

Mounted upon the above described frame in any suitable fashion is a motor structure indicated as C, the details of which form no part of the present invention and therefore are not herein described in detail. C1 indicates a motor shaft and C2 generally indicates a clutch structure controlled for example by the manual lever C3.

D generally indicates the transmission structure which may for, example include the transmission housing D1 in which may be positioned any suitable gear reduction. D2 indicates a shaft extending from the clutch structure C2 which is in driving relation with 'the gear reduction.

D3 indicates a shaft from the gear reduction which carries the sprockets D4 about which pass the sprocket chains D5 to the lower sprockets D6 which drive the drill head or shaft D"',rin

which may be removably positioned any suitable driven by the pawl E6 on the rock lever EFl i which is oscillated by the arm EB and the link E9 rotatably mounted upon the arm E1o on the shaft D3. It will be understood that the work may be forwardly fed manually, when the machine is not This feed mechanism may in operation, by employment of the manual crank E11 upon the shaft E1. This manual feed may be employed to move the drill forwardly into contact with the rail and may also be employed to withdraw it from contact with the rail after the drilling operation is completed. During the drillf ing operation proper the feed is in response to rotation of the crank E10. The feed mechanism and the shaft D7 are mounted in a Channel member E12 supported by angles E13 from the main frame members B1. the sides in the structure so formed, being for example welded thereto.

G generally indicates an abutment member for engaging the opposite side of the rail from that which is being drilled. It includes for example 'the upwardly inclined fork members G1, the transverse connecting structure G2 with the adjusting set screw or bolt G3 and the downwardly extending arm G4. The arm G1 forks at its lower end as at G5, the tines of the fork G5 inclining inwardly as well as downwardly and terminating Pins El4 project outwardly from i in rail engaging studs or enlargements G5. G7 G7 indicate securing ends on the forks G1, which are notched on their lower edges as at G5, to seat upon the pins E14. By employing a plurality of notches it will be seen that a longitudinal adjustment of the drill structure in relation to the fork or abutment member is permitted. By the employment of open notches a ready removability of the abutment from the drill structure is also provided. The screw G3 serves to adjust the height of the fork in relation to the rail and permits lining up of the members G6 in line with the axis of the drill. The fork in the members G5 permits the drill to pass entirely through the rail without interruption from the abutment.

H indicates a base structure which includes the plate H1 and the angles H2 H2 extending from one end thereof, the members H2 being connected by the transverse brace or angle H3. H4 H4 are brackets upwardly extending from the members H2, having slots through which may pass the pivot pin H5. This pivot pin passes also through brackets H5, the upper ends of which are secured to the side frame members B1. It will thus be seen that the drill supporting structure above dethat the drill supporting structure above described is pivotally mounted upon the base members H1 H2. In order to e'ect an adjustment of the drill supporting structure in reiation to the base I employ the following mechanism. Mounted at the outer. end of the member H is a cup H7 adapted toV receive the head HB of the socket H5, the head being held against escape from the cup for example by the pins H10. Pinned to the socket H9 is the screwthreaded shaft H11 which passes through the screwthreaded member or nut H12. This screwthreaded member H12 may be mounted upon or welded to one of the transverse channel members H13 which serve as supports from the'gear reduction housing D1 previously described. H14 is an aligning bearing for the upper portion of the shaft H11 and H15 is a manual handle pivoted as at H15, to the upper end of the shaft H11. It will be understood that rotation of the shaft H11 will cause the main frame and the Vdrill structure mounted thereon to be tilted upwardly or downwardly in relation to the base members H1, H2. rInasmuch as the drill structure is removed from the pivot pin H5 this tilting of the drill supporting structure causes an upward or downward adjustment of the drill in relation to the base member H. In order to permit the drill to reach the lowest possible adjustment the channel member E12 is cut away as at E20, as shown for example in Figure 4, to permit the passage therethrough of the member H1 when the device is at its lowest adjustment.

Pivoted for rotation about the pin H5 are the arms J connected by the transverse member J1 the whole forming an H-shaped structure. At one end of the H is a. pivot pin J2, mounted upon which is the track engaging roller J3, flanged at each side as at J4. The opposite ends of the arms J are apertured asV at J5 to receive the passage therethrough of the locking pin J5 having the offset end or handle J7. One end may be split as at J8 to give a frictional or gripping engagement with the apertures through which it passes. Each of the brackets H5 is apertured as at J 9 to permit the passage of the pin J5. The side frame members B1 are similarly apertured as at J10. It will be understood that by employment of the pin J5,

`passing-through the said apertures, the arms J,

and thus the wheel J3, may be secured selectively in the operative position in which they are shown in dotted line in Figure 1, or in the inoperative position in which they are shown in full line in the same gure.

It will be realized that whereas I have shown and described a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my speciiic showing. In particular it will be understood that although I have shown my drill and abutment structure as adapted for and applied to use with railroad rails, I do not wish to be so limited, since the same structure may be employed for other purposes and in other connections.

The use and operation of my invention are as follows:

I have provided a drilling structure which is particularly adapted to use upon railroad tracks, rails and the like, although I do not wish to limit it toA such use. It includes the base structure H1 H? which may rest for example upon the roadbed or upon the ties and which serves as a support or base for the whole structure when in use. The main frame or drill supporting structure, including the side frame members B1, is pivoted as a unit for rotation about the pivot vr105 pin H5. The drill proper is at the end of the main frame remote from the said pivot and therefore rotation of the main frame imparts a substantially vertical movement to the drill, upwardly or downwardly in relation to the track. .1.10 This4 adjustment may be obtained by rotation of the screwthreaded shaft H11 which seats in the cup H7 on the member H1. ReferringY for example to the position of the parts in Figure 4, rotation of the'shaft H11 will lift the drill shaft and,1.15 head D7 to any'desired height in relation to the object being drilled, in this instance a rail. In order to permit the employment of a light drill and drill supporting structure, of insufficient weight to hold itself in position, and not fastened ..120 down, I employ the abutment structure gen erally indicated as G. The forks G1 are hooked over the pins E14, the slots G11 providing a longi# tudinal adjustment, depending upon which slots lengage the pins E14. The ready removability of r the abutment member G is an advantage, since the end may be hooked into restricted spaces, such as the space between the two rails shown in Figure '7, which it will be unable to penetrate were it xed in relation to the heavy and rela- .130 tively immobile drill structure. For example the hook may be slid in between two rails or tilted vinto position to penetrate between two rails.

When positioned in the restricted space it may then be hooked to the pins E14. Preferably the 135 abutment members G6 of the fork arms G5 are horizontally aligned with the axis of rotation of the drill. This alignment may be obtained by rotation of the screw G3. Thus I may compensate for rails of diierent height, and for different ,140 adjustments in height of the drill. The drill member may pass entirely through the web of lthe rail, since it will pass between the fork one of the rails and to support a part or substantially all of the weight. In such a case one man may wheel the device like a wheelbarrow along the rail, or two men, one at each end, may guide the device, the weight being supported by the wheel. When the device is in operative position the wheel is swung into the full line position in which it is shown in Figure 1.

I claim:
